Ubuntu has never been an option for me and all of my various hardware - it simply didn't work. It booted fine, but then there was always some GUI-related problems, everything was constantly restarting, X server was crashing ...

Nowadays I still don't use Ubuntu, because it still doesn't work on my hardware [even an upgraded one], and the Unity interface is the heavy nightmare.
There are so many simple, lightweight, configurable and efffective GUIs. I'm shocked they choose Unity.
I'm even shocked that Ubuntu is [*cough* still] most popular linux distribution.
I still remember the times when Ubuntu was a young startupper. I was using other OSs at the time, but I though it would be nice for linux OS to be more recognizable in the OS world. Too bad it's Ubuntu that tries to fulfill that mission ...
